Understand the fundamentals of human risk assessment with this introduction and reference Human risk assessments are a precondition for virtually all industrial action or environmental regulation, all the more essential in a world where chemical and environmental hazards are becoming more abundant. These documents catalog potential environmental, toxicological, ecological, or other harms resulting from a particular hazard, from chemical spills to construction projects to dangerous workplaces. They turn on a number of variables, of which the most significant is the degree of human exposure to the hazardous agent or process. Human and Ecological Risk Assessment combines the virtues of a textbook and reference work to introduce and analyze these vital documents. Beginning with the foundational theory of human health risk assessment, it then supplies case studies and detailed analysis illustrating the practice of producing risk assessment documents. Fully updated and authored by leading authorities in the field, the result is an indispensable work. Readers of the second edition of Human and Ecological Risk Assessment will also find: Over 40 entirely new case studies reflecting the latest in risk assessment practice Detailed discussion of hazards including air emissions, contaminated food and soil, hazardous waste sites, and many more Case studies from multiple countries to reflect diverse international standards Human and Ecological Risk Assessment is ideal for professionals and advanced graduate students in toxicology, industrial hygiene, occupational medicine, environmental science, and all related subjects.

This Test Guideline describes methods to determine the surface tension (in N/m) of aqueous solutions. The methods are based on the measurement of the force which it is necessary to exert vertically on a stirrup or ring, in contact with the surface of the liquid, in order to separate it from the surface, or on a plate, with an edge in contact with the surface, in order to draw up the film that has formed. There are four different methods: the plate method, the stirrup method, the ring method and the OECD harmonized ring method. They are described in detail in the ISO Standard 304-1985. The methods described are applicable to aqueous solutions of most substances regardless of their degree of purity. The concentration should be 90% of the saturation solubility, but must below 1g/l. This shall therefore be carried out under a protective cover to avoid interference at 20°C approximately. The ring is immersed below the surface of the solution. Then the table top, where the measurement vessel is placed, is lowered gradually and evenly at a rate of approximately 0.5 cm/min to detach the ring from the surface until the maximum force is reached. The force is read on the tensiometer. After completing the first measurement, measurements are repeated until a constant surface tension value is reached.
